Misprints of King's books aren't worth too much. They occur quite frequently, although I've never heard of one such as you describe. The most common seems to be when a duplication of signatures is bound. There is a small market for these oddities, though. You might put it up on eBay, if you want to sell it, to see what it would bring. King's signature is normally worth about $100-200.

According to my records, about 1.5 million copies of Dolores Claiborne were in the first printing. It is not a scarce item, and with that quantity, I'm not really surprised an error got released.

My pleasure, Cope. You might also want to check out http://www.TheDarkTower.com/palaver. It's one of the biggest Stephen King bulletin boards around, and there are lots of collectors there in the Calvin's Corner forum. (Tomas, if you don't want me to plug that site, just delete this!)

Of course there's no reason to not come to me as well you can visit BOTH sites every day... Go ahead and bookmark mine while you're reminded to. For firefox users there's a great add-on called "Morning Coffee" that opens up whatever websites you want with one click. Make sure to add me in there... I do!
